in Bottle-Stoppers, of which the following is a full, clear, and exactdescription.

This' invention relates tobjottle and jar Stoppers or closures 'of thatparticular class comprising a metallic cap containing a packing vdiskand havin@ means for securing it externally to the nec or mouth of thebottle,

with the packin disk duly compressedto form a hermetic sea Bottles whichare usually Asealed with this kind of a sto per are of comparativelythick and heavy g ass to`withstand the internal pressures, inconsequence. of which, the width or thickness of the glass at the lipsof the bottle upon which the packing rests is considerable, and thepacking disk which has heretofore been used has eX-'\ tended across thediameter of the mouth of the bottle and overlaid theV entire thicknessof the lips of the bottle. I have discovered that an effective seal canbevobtained in this type of' stopper with a acking disk of less diameterthan those use heretofore, and by' making use of this discovery, I amable to economize very considerably in the amount of cork or otherpacking materialwhich is used, which becomes an item of considerable'importance in the `manufacture o1 large numbers of these stop ers. Thiseconomy in the manufacture is t e principal object of the presentinvention, and the means for accomplishing it will now4 be described indetail. i,

In the accompanying drawing, Figure 1 is a side elevation'of a form 'ofstopper of my own invention, modified to receive the pack-v ing disk ofreduced size and constituting the present invention Fig. 2 is a plan ofthis' sto per looking at the bottom or inside another type of t 1e same.Fig. 3 -is a section of the same stopper taken on line --zv of Fig. 2,as apphed to an ordinary commercial form of bottle; and Fig. 4 is asectional'view of of stop er showing my img disk o reduced size appliedproved pac It is to be understood that the improvements herein describedin the packing disk are applicable to any of the types of stop ercomprising the metal cap and having suita le other material.

as shownat means to engage with the usual external annular shoulder onthe bottle.

a represents the-metal cap, and b a flange depending therefrom andsuitably shaed with inwardly bent lips, asin Figs. 1, 2, en 3,

or with corrugations as in Fig.v 4, or in any other conformation, which,when forced inward by the crippling machine, will the` shoulder c on tottle.

e represents the improved packing dik, ordinarily of cork, but whichmaybe of any This packing dlskfiustead of being of a diameter equal tothe internal diameter of the cap, is substantially smaller than thediameter of the cap, but greater than the bore of the neck of thebottle, so that instead of extending fully across' the top or lips d ofthe bottle, it rests at 'itsedge on top of the inner half or innerportion of the lips of the bottle. The vdisk ,is therefore placed andsecured concentrically in the metal cap, and leaves an annular spacearound. its ed e which heretofore has been occupied by t e larger disk,and which determlnes the amount of saving of c ork or other materialwhich is eliected by my invention.

i In order to secure the disk in the ca I annularly depress the outercorner of t e 'ca so that the top of the cap w' form a circuiyar seat ofthe ri ht size to reessere ceive thedisk, and the disk is t en securedinthis seat either by cement or by bending 1nward tongues of the metalnear the edge of the disk and orcin tongues `into or un er the cork.These tongues are indicated by i, and may be given an other desiredshape, and may, infact, be

the points of said P su stituted by embossings, which would.-

have'the same efect.

In Fi 4', the 'metal cap is shown ofthe usual fu l size acrossthe top,the disk being merely cemented in a concentric position to theflat.inner surface of the cap.

When a'cap equipped with this small disk is applied to the bottle, the'edge of the'disk overreach'es the inner portions` or surfaces of the'lips d of the bottle, as clearly shown in Fie. 3. The contactin surfacebetween the disk and the bottle whie being smaller in egitent than intheStoppers heretofore used, is, 1

nevertheless, sucient toe'eetively seal the bottle, m discovery beingthat any larger surface o contact between the disk and' bot tle, such as'heretofore used, is superfluous,
